How to Fix Epson ET-8550: Can Error Code 031006 be related to Scanner?

Question: I bought a used Epson ET-8550, and when I power it up, it displays error code 031006. I would like to get this printer repaired. It seems like the error pops up while the printer is trying to "home" the scanner. I have another EcoJet, and when you power it up, the scanner moves around a bit, then the print head and other motors move. On the new one, the scanner moves a little, looks kind of jerky, then stops, beeps, and the error comes up. The print head never moves, and nothing else inside the printer moves. Everything I search about this code points to the mainboard or the print head. Do you know what exactly the error code means? Could it be that the printer isn't able to home the scanner and thus cannot initialize?

Error code 031006 on the Epson ET-8550 usually indicates a "Head fuse broken error" or "Printhead failure." The error code itself is related to the mainboard and not directly to the scanner. However, the sequence of checks that the printer performs during startup could make it seem like the scanner is involved.

Upon startup, the printer first checks the head fuse. If there is an issue here, the error code 031006 will appear, preventing further initialization. After the head fuse check, the printer proceeds to check other components, including the waste tank, whole bunch of things, and then the scanner. If the head fuse check fails, the printhead and other motors will not move, which aligns with the symptoms you described.

Common causes of error code 031006 include:

• A damaged or faulty mainboard
• Loose or disconnected cables
• A power surge or electrical problem
• Dust or debris buildup in the printer

Here's a step-by-step guide on how to troubleshoot and repair error code 031006 on your Epson ET-8550 printer:

Step 1: Uncase the Printer Begin by uncasing the printer to access the mainboard. Follow the instructions in the user manual or refer to online video tutorials. Ensure the printer is turned off and unplugged before starting this process.

Step 2: Remove the Mainboard Carefully disconnect all cables and connectors from the mainboard, noting their positions for later reassembly. Unscrew and remove the mainboard from the printer.

Step 3: Inspect the Mainboard Examine the mainboard for any visible signs of damage, such as burnt or broken components, loose connections, or corrosion. If you detect any damage, the mainboard may need to be repaired or replaced.

Step 4: Repair or Replace the Mainboard If the mainboard is damaged, you can either repair it if you have experience with electronics or replace it with a new one. If repairing, replace any damaged components or fix broken connections. If you're not comfortable with this, seek help from a professional technician or contact Epson support.

Step 5: Reassemble the Printer After repairing or replacing the mainboard, reassemble the printer. Carefully reconnect all cables and connectors, following the user manual or video tutorial for proper placement. Secure the mainboard back into place and recase the printer.

Step 6: Test the Printer Plug the printer back in and turn it on to check if error code 031006 has been resolved. If the issue persists, you may need to repeat the process or seek further assistance.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. For instance, resolving a simple clog might involve advice on unclogging procedures. However, if the printer remained inactive during downtime, a comprehensive service for the ink system could be necessary. Situations like a "paper jam" can arise from hundreds of potential causes, and solving such an issue has become something of an in-office jest. So, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis. So, it might take a few weeks before we can get your printer to drop it off or mail it to us. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed if you opt for mail-in or local drop-off services. However, we acknowledge that our rates aren't the most economical. Thus, we highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel’s homepage (https://youtube.com/@bchtechnologies). Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.
